The COLECO Chameleon twitter account is still up and running...
My theory is that:
1) you cant temporarily take down a twitter page to rework it, like you can with fb, without deleting it
and MK is still planning the comeback of the year decade CENTURY and doesnt want to lose his follower count.
or the much, much, simpler, funnier guess..
2) This "professional" "Retro expert filled" bastion of a company....forgot their twitter password.
